RUNNING THROUGH CURVES

Economic considerations demand high average, rather than occasional high maximum speeds. Rapid acceleration and retardation are essential and vehicles must also be able to negotiate curves at high speeds, which is of particular importance for lines with many curves. The forces acting on a vehicle running in a curve are shown and the limiting valves of speed and the effect of axle load on speed through curves are established mathematically. Transverse flexibility is important in reducing dynamic forces at curve irregularities. Time-speed and time-distance curves for a single car and for a car and trailer are plotted for electric hydraulic and mechanical transmissions.
